In the underwater Dagon dungeons, I’ve encountered two issues:
I got hit with a sandstorm (yep, sounds crazy but it happened)
The bosses seem to be getting stuck on the walls and not attacking. If you can push them back against a wall or especially in a corner, they just freeze and don’t do anything.
The sandstorm was there and long before the dregs will also get hit by the sands think it has been around for a long time but for all dungeon carry a you been warned
